**Sievers' Unique Gas Permeable Membrane Conductivity Measurement Method** In the conductivity measurement method of the TOC analyzer, the conductivity indicated by the carbon dioxide (carbonate ions) produced after the oxidation and decomposition of organic matter is measured to calculate the carbon concentration. The Sievers TOC analyzer employs a separation measurement mechanism for carbon dioxide called the "gas permeable membrane module," which uses a thin Teflon film to separate carbon dioxide from the sample water into the pure water line within the analyzer, enabling accurate TOC measurements free from the influence of other ions.
